In this work, surface modification technique with coupling agents and anchoring polymerization was adopted to tailor the surface properties of nanoscaled titanium dioxide (TiO 2 ). Ethyl glycol sols with TiO 2 were prepared in order to simulate the dispersibility of differently modified TiO 2 in a molten polyamide 6 (PA6) matrix. The modified TiO 2 were melt compounded with PA6 and composites and fibers were prepared. The average filler diameter of 47 nm (in composites) and 44 nm (in fibers) indicated homogeneous dispersion of TiO 2 in the matrix, whereas unmodified TiO 2 showed agglomerated structures in the PA6 matrix. The mechanical properties of the composite fibers were improved as compared to pure PA6 fibers and composite fibers with unmodified TiO 2 .
